Hello,
I'm not expert in ASA and routing so I ask some support the following case.
There is a Cisco VPN client (running on Windows 7) and an ASA5505.
The goals are client could use remote gateway on ASA for Skype and able to access the devices in ASA inside interface.
The Skype works well but I cannot access devices in the interface inside via VPN connection.
Can you please check my following config and give me advice to correct NAT or VPN settings?
ASA Version 7.2(4)

config#no nat (inside) 1 10.0.0.0 255.255.255.0 < This is not required.
Need to add - config#same-security-traffic permit intra-interface
#access-list extended nonat permit ip 192.168.1.0 255.255.255.0 10.0.0.0 255.255.255.0
#nat (inside) 0 access-list nonat
Please add and test it.
Thanks

Hi Ajay!
Thank you for fast answer!!! It was very helpful!
The correct access list command #access-list nonat extended permit ip 192.168.1.0 255.255.255.0 10.0.0.0 255.255.255.0
The new config works like a charm
Best regards,
